Question:

In the circuit shown in Fig. 3.45 the sources have emf's ε1 = 1.5 V, ε2 = 2.0 V, ε3 = 2.5 V, and the resistances are equal to R1 = 10Ω, R2 = 20Ω, B3 = 30Ω. The internal resistances of the sources are negligible. Find:
(a) The current flowing through the resistance R1;
(b) A potential difference φA €“ φB between the points A and B.
